BACKGROUND

Electronic payment refers to the circulation and payment of funds realized in a computer network system in the form of electronic data storage and transfer by taking commercial electronic tools and various kinds of electronic money as media, and taking computer and communication technology as a means.

With the combination of Internet, mobile communication and computer and the other technologies in recent years, mobile payment on behalf of mobile electronic commerce emerges as the times require. As an emerging electronic payment manner, the mobile payment is advantaged in that it can be carried out anytime and anywhere, conveniently and fast, and its cost is low, etc. As long as a consumer has a mobile phone, the consumer can complete financing or trading, and enjoy the convenience brought by the mobile payment. Nowadays, the mobile payment is becoming a new highlight in electronic commerce.

In addition, a recent survey shows that 82% respondents are worried that if their mobile phones are lost or stolen, someone may carry out fraud by making use of the information stored in these mobile phones (including smart cards). Meanwhile, 90% respondents are worried that their personal data and financial data may be lost after their mobile phones are lost; and 72% respondents admit that the information stored in their mobile phones is very important and irreplaceable. Since subscribers use mobile phones to engage in various different activities, such as electronic payment and the like, it is really a disaster for subscribers if their mobile phones are lost. In this survey, 91% respondents say the loss of mobile phones for electronic payment will bring serious losses to them. Meanwhile, as people increasingly depend on mobile phones, the operator is required to make their own subscribers feel secure.

FIG. 4 shows a schematic diagram of a status machine at a network side according to the embodiment of the present application. FIG. 5 shows a schematic diagram of a status machine at a terminal side according to the embodiment of the present application.

As shown in FIG. 2, with reference to FIG. 4 and FIG. 5, the method for remote control of a smart card comprises:

step S1, the subscriber applies to the smart card management platform for destroying the smart card;

step S2, the mobile network platform and the terminal side (the terminal, the smart card) perform interactive signaling processing; and

step S3, the terminal side completes destroying the smart card.

FIG. 7 shows a preferred flowchart of the method for remote control of a smart card according to the embodiment of the present application; with reference to FIG. 7, the step S2 may comprise the following processes:

step S100, after receiving the request to destroy the smart card sent from the subscriber to the smart card management platform, the management platform matches information of the smart card with information in the database to determine if the smart card is valid; if the smart card is invalid, then the management platform returns a failure message and the current processing flow is ended; and if the smart card is valid, then the next step is executed;

step S102, the smart card management platform looks up current status information of a mobile station where the smart card is positioned via the mobile network platform; if the mobile station where the smart card is positioned is in a normal turned-on status, then the mobile network platform directly sends a destroy command to the mobile station where the smart card is positioned, and, after the mobile station where the smart card is positioned executes the destroy command to destroy the smart card, the mobile station returns a success message to the mobile network platform, and the mobile network platform changes the status of the smart card to a destroyed status and informs the smart card management platform to update the status of the smart card to a destroyed status; if the mobile station where the smart card is positioned is in an off-line status (in a turned-off status, or in an turned-on status but not in a service area, and the like), then the mobile network platform updates its status to an awaiting-destroy status, and informs the smart card management platform to update a status database; and

step S104, after the mobile station where the smart card is positioned in an off-line status (in a turned-off status, or in an turned-on status but not in a service area, and the like) is turned on or enters the service area, when it registers with the mobile network platform, the mobile network platform makes a query and finds that the mobile station where the smart card is positioned is in an awaiting-destroy status, and sends a destroy command to the mobile station where the smart card is positioned; after executing the destroy command to destroy the smart card, the mobile station returns a success message to the mobile network platform, and the mobile network platform updates theist status to a destroyed status and informs the smart card management platform to synchronously update the status database.

In the method, before the mobile station where the smart card is positioned executes the destroy command sent by the mobile network platform in step S102/S104, a security authentication should be included in order to confirm the command is the destroy command sent by the smart card management platform.

FIG. 6 shows a schematic diagram of signaling interaction in a system according to an embodiment of the present application; as shown in FIG. 6, signaling interaction between a subscriber and the mobile network platform is realized through signaling as shown.

In the method, the step S102 that the mobile station where the smart card is positioned executes the destroy command to destroy the smart card comprises:

the mobile station disables the function of the smart card permanently by destroying physical (or the small card) hardware; and

the mobile station destroys the smart card by executing a preinstalled software procedure (device).

When the mobile station destroys the smart card by executing a preinstalled software procedure, the preinstalled software procedure (device) can either be preinstalled in the smart card, or be preinstalled in the mobile station where the smart card is positioned.

For example, in a method for destroying a smart card by destroying hardware, the voltage of a mobile phone battery is directly applied to the power supply circuit of the smart card; since the normal voltage of the smart card is quite lower (1.8 v/3 v), while the operating voltage of a mobile terminal is generally 3.6 v to 4.2 v (other destroy methods can be employed for a card under 5 v), the smart card can be destroyed directly, and cannot be repaired.

The software procedure is preinstalled in the terminal where the smart card is positioned, and the step that the mobile station executes the destroy command is as follows:

destroying payment data in the smart card (the memory where the payment data is stored); and

executing the preinstalled software procedure in the terminal to destroy a payment data smart card program in the smart card:

the software procedure is preinstalled in the smart card, and the step that the mobile station executes a command to destroy the payment data in the smart card is as follows:

copying the preinstalled software procedure in the smart card into the terminal;

destroying the payment data in the smart card (the memory where the payment data is stored); and

executing the copied software procedure in the terminal, which is a back-up program of destroying the smart card.

For example, if the smart card is to be destroyed by a software program, the software program may be written to make the number of times of inputting PUK codes greater than 10, then the smart card is permanently locked and cannot be unlocked, namely the smart card is destroyed.

In step S102 that the smart card management platform looks up the current status information of the mobile station where the smart card is positioned via the mobile network platform, the mobile network platform finds the status information of the mobile station according to the mobile identification code and the location regional information of the mobile station.

Step S104, after the mobile station where the smart card is positioned in an off-line status (in a turned-off status, or in an turned-on status but not in a service area, and the like) is turned on or enters the service area, when it registers with the mobile network platform, the mobile network platform makes a query and finds that the mobile station where the smart card is positioned is in an awaiting-destroy status, and sends a destroy command to the mobile station where the smart card is positioned; after executing the destroy command to destroy the smart card, the mobile station returns a success message to the mobile network platform, and the mobile network platform updates its status to a destroyed status and informs the smart card management platform to synchronously update the status database.

According to another aspect of the present application, a method for destroying a smart card remotely based on an electronic payment service is provided (in this method, a subscriber does not need to apply, but the management platform directly handles the destroying of a smart card of the subscriber, which is corresponding to the case that the smart card is used illegally by the subscriber).

FIG. 3 shows a preferred flowchart of the method for remote control of a smart card according to an embodiment of the present application; FIG. 8 shows a preferred flowchart of the method for remote control of a smart card according to an embodiment of the present application.

As shown in FIG. 3, with reference to FIG. 8, the method for remote control of a smart card comprises:

S11, if the smart card supervision mechanism (such as the payment system platform or the smart card management platform) finds that a subscriber uses the smart card illegally, the smart card supervision mechanism informs the mobile network platform to process this case;

S12, the smart card management platform performs short message interaction with the terminal side where the smart card is positioned via the mobile network platform to execute the destroying of the smart card; and

S13, the terminal completes the destroying of the smart card.

Wherein step S12 may comprise the following processes:

the smart card management platform looks up the current status information of the mobile station where the smart card is positioned via the mobile network platform; if the mobile station where the smart card is positioned is in a normal turned-on status, the mobile network platform sends a destroy command to the mobile station where the smart card is positioned directly: after the mobile station where the smart card is positioned executes the destroy command to destroy the smart card, the mobile station returns a success message to the mobile network platform; the mobile network platform changes the status of the smart card to a destroyed status and informs the smart card management platform to update the status of the smart card to a destroyed status; if the mobile station where the smart card is positioned is in an off-line status (in a turned-off status, or in an turned-on status but not in a service area, and the like), the mobile network platform updates its status to an awaiting-destroy status, and informs the smart card management platform to update the status database;

step S404, after the mobile station where the smart card is positioned in an off-line status (in a turned-off status, or in an turned-on status but not in a service area, and the like) is turned on or enters the service area, when it registers with the mobile network platform, the mobile network platform makes a query and finds that the mobile station where the smart card is positioned is in an awaiting-destroy status, and sends a destroy command to the mobile station where the smart card is positioned; after executing the destroy command to destroy the smart card, the mobile station returns a success message to the mobile network platform; the mobile network platform updates its status to a destroyed status and informs the smart card management platform to synchronously update the status database.

In the method, before the mobile station where the smart card is positioned executes the destroy command sent by the mobile network platform in step S402/S404, a security authentication should be included in order to confirm the command is the destroy command sent by the smart card management platform.

In the method, the step S402 that the mobile station where the smart card is positioned executes the destroy command to destroy the smart card comprises:

the mobile station disables the function of the smart card permanently by destroying physical hardware; and

the mobile station destroys the smart card by executing a preinstalled software procedure (device).

When the mobile station destroys the smart card by executing a preinstalled software procedure, the preinstalled software procedure (device) can either be preinstalled in the smart card, or be preinstalled in the mobile station where the smart card is positioned.

For example, if the smart card is to be destroyed by destroying hardware, the voltage of the mobile phone battery may be directly applied to the power supply circuit of the smart card; since the normal voltage of the smart card is quite lower (1.8 v/3 v), while the operating voltage of the mobile terminal is generally 3.6 v to 4.2 v (other destroy methods can be employed for the card under 5 v), the smart card can be destroyed directly, and cannot be repaired.

The software procedure is preinstalled in the terminal where the smart card is positioned, and the step that the mobile station executes the destroy command is as follows:

destroying payment data in the smart card (the memory where the payment data is stored);

executing the preinstalled software procedure in the terminal to destroy a payment data smart card program in the smart card;

the software procedure is preinstalled in the smart card, and the step that the mobile station executes a command to destroy the payment data in the smart card is as follows:

copying the preinstalled software procedure in the smart card into the terminal;

destroying the payment data in the smart card (the memory where the payment data is stored);

executing the copied software procedure in the terminal, which is a back-up program of destroying the smart card.

For example, if the smart card is to be destroyed by a software program, the software program may be written to make the number of times of inputting PUK codes greater than 10, then the smart card is permanently locked and cannot be unlocked, namely the smart card is destroyed.

In addition, step S402, the smart card management platform looks up the current status information of the mobile station where the smart card is positioned via the mobile network platform, and the mobile network platform finds the status information of the mobile station according to the mobile identification code and the location regional information of the mobile station.

Step S404, after the mobile station where the smart card is positioned in an off-line status (in a turned-off status, or in an turned-on status but not in a service area, and the like) is turned on or enters the service area, when it registers with the mobile network platform, the mobile network platform makes a query and finds that the mobile station where the smart card is positioned is in an awaiting-destroy status, and sends a destroy command to the mobile station where the smart card is positioned; after executing the destroy command to destroy the smart card, the mobile station returns a success message to the mobile network platform; the mobile network platform updates its status to a destroyed status and informs the smart card management platform to update synchronously the status database.
